1, aging aluminum temperature setting and control: Generally, the aging temperature and the apparent temperature there is a certain error, set the table temperature according to the actual temperature of the oven to set, and pay close attention to the temperature fluctuations.
2, aluminum aging insulation: to be strictly in accordance with the requirements of the process to aging, holding time should be appropriate to prevent under-aging or over-aging and lead to not enough hardness. Blank box, loading furnace.
3, aluminum aging extrusion frame can not be too close, there should be spacing between the material and the material, especially the
aluminum plate is not ventilated material, thicker material interval to be larger, tube material and small material, sheet combined with a box When the tube material down surface is conducive to aging air circulation.
4, aluminum aging furnace before the furnace to 6xxx other special alloy and ordinary 6063 alloy separately furnace aging, because of the production of the furnace is indeed time-limited, to take a special alloy process for aging.
Extrusion produced aluminum, low hardness before aging is not used as a finished product, therefore, in general, must be time-intensive to improve strength. Usually, aging can be divided into two kinds of natural aging and artificial aging, aluminum 6xxx aluminum production is still basically the latter.
